Abstract: 1,016,399. Hydrodynamic torque converters. E. A. SALO. Dec. 31, 1963, No. 51315/63 Headings F2C and F2D. An hydrodynamic torque converter for use between an electric motor and a pump to provide high overdrive speeds comprises an impeller 12 fast on an input shaft 16 and having radial blades 46 with concave leading sides and convex trailing sides defining radially outwardly narrowing fluid channels 44 discharging to radially outwardly narrowing channels between blades 40 of a turbine 14 fast on an output shaft 30, the blades 40 having convex leading and concave trailing sides. Fluid leaving the turbine 14 returns to the impeller through guide vanes 150 in stationary return ducts 54 cooled by a single annular water-cooling section 56, and variable incidence radial control vanes 58. The incidence of the control vanes 58 is varied to maintain a substantially zero tangential discharge velocity from the turbine blades by an output-driven centrifugal governor 70 which through linkwork 84, 114, turns a common bevel gear ring 116 meshing bevels on the radial vane-spindles. The governor acts conjointly with a pair of diaphragms 134, 136, sensitive to pressure on opposite sides of one of the guide vanes 150, the diaphragms serving to position, through springs 152, 154, the fulcrum of a floating lever 108 in the governor linkage. A handscrew adjustable setting 104 for the fulcrum of a bell-crank 94 in the linkage provides a datum. Phosphate ester-type fluid is used to permit high operating temperatures.

A commutator is made from a length of copper bar 10 by bending the bar into a ring 14, electron beam welding the adjacent edges 11, 12 together and extruding the ring blank 15 in an extrusion press to form an elongated member 17 which is thereafter formed into a commutator by machining. The bar is bent into a W-cross-section before being formed into a ring and the edges 11, 12 are tapered to provide parallel faces for welding. The welding is pe:- formed on a group of rings mounted on a bar 23, Fig. 2, and advanced past an electron beam welding device 21. The device is housed in a vacuum chamber 20 at 10 to 100 microns pressure. The blank is then annealed at 900‹ F. for 20 to 30 minutes and rinsed in dilute acid to etch it after which it is washed in soap solution which adheres to the blank surface to act as a lubricant for the extruding. The extrusion press comprises a die (33), Fig. 3 (not shown), on which the blank (15) is seated and a mandrel (36) and ram (35) which co-operate to force the blank into the die.

Title: A material positioning device for sequential sewing apparatus
IPC: D05B41/00
Filed: 1965-12-16
Abstract: 1,128,780. Sewing-machines. A. J. MIT CHELL CO. 16 Dec., 1965 [19 Jan, 1965], No. 53492/65. Heading D1G. In a sewing machine a feed for moving work between successive sewing operations, e.g. attaching buttons or fasteners, or sewing button-holes, comprises an intermittently rotated drum having at least one clamp for securing the leading edge of the material. In the preferred embodiment the drum 5 is mounted adjacent a sewing machine 1 and is provided with two pivoted clamps 7, 7a. The clamps are normally urged against clamp pads, but may be raised by fixed and movable cams 74, 73 respectively, engaging actuating mechanism 67-71. The work is guided to the drum by guides 8, 13 and tensioned by a pivoted weighted arm 15. The extent of successive rotation of the drum is determined by adjustable switch actuating cams arranged around the inside of the drum. In the rest position solenoid armature engages a slot in the rear face of the first cam. The edge of the material is placed below the clamp and a start button depressed. Cam 73 is thus withdrawn so that the clamp secures the edge of the material, and sewing of a button is commenced. As the sewing operation finishes the armature is withdrawn and the motor started. When the drum has rotated a sufficient amount the next cam is held by engagement with the armature, and the motor is stopped. A new sewing operation is commenced if a sensing arm 23 detects the previously sewn button. D.C. current is momentarily applied to the motor to briefly urge the drum hard against the armature to tension the work. Thereafter there is sufficient play of the stop in the cam to allow the button to be moved during the sewing operation. This sequence continues until the sewing cycle following engagement of the armature with the last cam has been completed. The drum is then rotated until the first cam is adjacent a further armature and a stop switch at the top of the frame. The end of the first workpiece is thrown manually over drop rail 10. A new workpiece is placed in position, and a new sequence commenced during which the cams are arrested by the upper armature. The leading edge of the first workpiece is released automatically during the second sequence so that the work drops over the drape arm 12. The machine may be operated to sew one button and move the drum one position before it stops.

[Also in Division F2] Apparatus for securing a pierce nut N upon a plate P comprises a die 44 having a plate supporting surface 52 with a die cavity having a polygonal throat 54 communicating with a slug chamber 46, metal deforming means 58 located in the die cavity adjacent the throat and extending across corner regions of the throat and pressing means 40 for driving the polygonal shank 18 of a pierce nut N having leading cutting edges 22 through a plate mounted on the surface 52 to excise a polygonal slug from the plate and drive it into the slug chamber 46 whilst the metal deforming means 58 engage and displace the metal of the corners of the nut shank firmly against the underside of the plate as the shank advances into the slug chamber. As described the head and shank of a nut N or a threadless bush are both polygonal with the longitudinal corners of the shank and head unaligned (Fig. 1, not shown). The metal deforming means consist of the exposed edges 58 of a hard metal sleeve 56 within the cavity. Dome 42 deforms the excised slug so that it will not jam on ejection from the cavity by means of compressed air through channel 50. The shape of the press and die are such that the final action before withdrawal of the press is the embossing of the plate P about the fastened nut N (60, Figs. 5, 6, not shown). Pin 48 locates the nut within the press. The press may comprise separate elements (62, 64, Figs. 7-9) for driving the nut and embossing the plate. The slug may be deformed by a pin (76, Figs. 14, 15, not shown) extending through the nut and connected to the nut driving part of the press by a lost motion device (80).

Abstract: 1,145,744. Road traffic signals. E. W. BLISS CO. 12 May, 1966 [12 May, 1965], No. 54060/65. Heading G4Q. A timing circuit in a traffic control system comprises a capacitor 22, Fig. 2, which charges through resistances 26 and 24 when a normally conducting transistor 34 is cut off by an input pulse; when the voltage across the capacitor is sufficient the unijunction transistor 18 conducts and discharges the capacitor through resistance 30 thereby producing an output pulse across this resistance. In response to this output pulse an external bi-stable circuit restores transistor 34 to conduction so that the capacitor 22 can complete its discharge through diode 32 and the transistor. This discharge circuit ensures that all the timed periods are equal; without it the first period would be longer than subsequent ones (Fig. 3, not shown) since the capacitor 22 cannot discharge completely through the unijunction transistor 18. Traffic control system.-Each of four signal lamps has associated with it a bi-stable circuit MM, Fig. 1, and a timing circuit TM. When the first bi-stable circuit MM1 is set it illuminates the corresponding lamp MSG and starts its timing circuit TM1. The output of the timing circuit sets the bi-stable circuit MM2 of the next phase; this re-sets the preceding bi-stable circuit MM1, illuminates its signal lamp MSC, and starts its timing circuit TM2.
